There has always been a lot of interest in accelerating brain function with the use of drugs and chemicals but I'm not aware of anything yet that stimulates the hippocampus to store long term memory.

This cycle repeats itself endlessly, and as a result the current through the circuit reverses direction repeatedly. This is known as an alternating current. This kind of reversal makes no difference to some kinds of loads. For example, the light bulbs in your home don't care which way current flows through them.
